When assessing EMC labs, if evidence did not exist this was being done, at least for transient tests, I would write a deficiency. Further, For tests such as surge, I expect to see synchronization with the both zero crossing points, not just the voltage transition from positive to negative..... I have seen many failures at lower levels that do not show themselves at higher levels. Derek N. Walton Owner, L. F.
